Abstract:A new perturbation technique is proposed, which, in contrast to the traditionalperturbation methods, does not require small parameters in the equations. In this method,according to the homotopy technique, a homotopy with an imbeding parameter isconstructed, and the imbedding parameter is considered as a "small parameter", so the pro-posed method can take the full advantages of the traditional perturbation methods. The resultreveals that the new method is very effective and simple, and it appears that even the first-ordersolution is of high accuracy.
